Venser, Shaper Savant - Great for lots of blue decks. Not only can it bounce any permanent of yours or an opponent's, it can also stop spells even if they say 'uncounterable'. Goreclaw, Terror of Qal Sisma - Good for any green deck running big creatures. Kiki-Jiki, Mirror Breaker - Good in many decks that contain red and etb creatures. Braids, Conjurer Adept - Show and Tell on a stick. I think it can fit in well in most chaos or theft-focused decks.
Others that are more niche that I use in the 99 of my decks that may not have places in most other decks: Surrak Dragonclaw - Decent sized body, makes my creatures uncounterable and serves as one of several trample enablers for my Maelstrom Wanderer deck. Seizan, Perverter of Truth - Helps out my Nekusar deck. Niv-Mizzet, the Firemind - Along with Curiosity and Psychosis Crawler, it is an alternate win-condition of sorts. I can also combine it with Notion Thief if I don't want to kill my opponents with their own cards, though doing so is very situational and I'd only do it if I'm not hurting myself with my own Spiteful Visions.
